In order to avoid and deal with today’s compliance and enforcement problems, it is no longer necessary to only understand environmental laws and regulations.  Equally necessary is understanding the entities involved, their focus, their strategies, objectives, and how to deal with them.  My approach integrates not only strong legal and regulatory knowledge, but also in depth understanding of the players and approaches, goals and objectives and methods involved in working with environmental regulators. 

For a more detailed understanding of how to communicate and deal with Environmental Agencies, please read  "Down the Rabbit Hole: Working with Environmental Regulators":

It has been 20 years since any major new environmental legislation has been passed, and the programs and regulations implementing them are well established.  Nevertheless, the numbers of inspections and ensuing enforcement actions have not diminished. Part of the reason for this can be attributed to increasing stringency and complexity of regulations, the growth of state and federal agencies involved, and the new approaches being taken.  This is often called the “Next Generation” of environmental compliance and enforcement.

“Next Generation Environmental Compliance and Enforcement”:










An attorney and federal senior executive service manager with 35 years of experience in both the private and public sectors. In depth knowledge of environmental science, policy, law, regulation, and litigation. Expertise in compliance and enforcement under all major environmental statutes and programs.  Extensive experience working with US EPA, DOJ, DOE, and State and Tribal environmental, agricultural and energy agencies.




I have broad and varied experience in the field of environmental protection, working as a scientist, attorney and manager. I have in depth knowledge of environmental issues, policies, laws and programs associated with air, water, waste, hazardous substances, pesticides, and toxics.  In particular, I have a unique understanding derived from working with numerous federal, state, tribal and local governments and private organizations in developing, implementing, and managing environmental programs.


While I have broad knowledge of all environmental programs, my area of expertise is with the national EPA compliance and enforcement program.  My work in this area has ranged from field level investigations and oversight to prosecutions of highly complex enforcement actions and litigation.  As an attorney and supervisory attorney I managed hundreds of cases and prosecutions undertaken both administratively and in court.  As a federal program manager I have intimate knowledge of the strategies and decision making processes that drive interactions, investigations and enforcement within state and federal governments.  As a lawyer and senior executive I developed and implemented compliance and enforcement programs, and authored national policies and strategies. I have interacted with and advised the most senior levels of state and federal regulatory agencies.  As an EPA senior executive I worked closely with all Regional and EPA HQ enforcement programs and managers and the U.S. Department of Justice (DOJ).


While I have worked as an attorney, supervisory attorney, manager and advisor at EPA and the Department of Energy (DOE), most recently I served as the Assistant Regional Administrator for the Office of Enforcement, Compliance and Environmental Justice in EPA’s Denver regional office. In this position I was the senior manager of a division of over 125 inspectors, case officers and attorneys responsible for oversight and enforcement in six states and extensive tribal lands. This entailed being involved with hundreds of investigations, prosecutions, negotiations and settlements conducted at the state, regional and national levels.  I have unique knowledge and perspective of the inner workings and dynamics of EPA, DOJ, and federal, state and tribal environmental, agriculture and energy agencies. For over 25 years I was involved in developing a broad range of investigatory and adversarial actions including criminal and civil administrative and judicial actions.


I have a deep knowledge of the development, implementation and management of national enforcement priorities and initiatives including those under the Clean Air Act, Clean Water Act, Resource Conservation Act, Superfund and Energy Extraction Initiatives. I have unique knowledge of the emerging focus on the oil and gas industry and the related enforcement and compliance issues affecting that sector.  Having designed and implemented many of these strategies, I am very familiar with the strengths and weaknesses of these initiatives and the emerging case law that effects their prosecution and settlement.  I understand the motivations, constraints and limitations of EPA, DOJ and other federal and state agencies
